Give an example of a specific trait of an animal

Multiple Choice

True or false: you get half of your chromosomes from your biological father and half of your chromosomes from your biological mother

• True

• False

Draw

Circle the #2 pair of chromosomes

Draw

Draw arrows to show where chromosomes came from.

Multiple Choice

Where are chromosomes found?

• In the mitochondria

• In the myostatin

• They’re all in the nucleus of the cells.

• On the proteins

Fill in the Blanks

A

is found in a certain region of a chromosome that causes a certain protein to be made

Draw

The different alleles of the genes (the genotype) determine the protein(s) that gets made. Circle a pair of allelles.

Multiple Choice

If an animal has typical muscles, what kind of myostatin protein does it also most likely have?

• Full Myostatin proteins

• Partial Myostatin proteins

• Full Myosin and Actin proteins

• One full and one partial myostatin protein

Multiple Choice

The partial myostatin protein does not fit into receptors on cells, so no message is sent, which results in_________ muscles.

• medium

• extra-big

• extra-small

• typical

Poll

• Not at all confident yet

• starting to get it

• Fairly confident I get most of it

• Super confident
